Find a can of Break Away, I have always been a faithful devotee of Kroil, but a seized Browning Auto-5 20ga choke made me a believer in Break Away.
Long story short, friend told me that he used Break Away on plow point bolts, almost guaranteed it to work. I ordered a can, 24hrs after I inverted the barrel into the Break Away filled pvc pipe I use to soak seized tubes, it screwed out with very little effort. Not much more effort than a well snugged tube.
It is the only thing I have found that works as good or slightly better than Kroil.
Stinks to me though.
